# StatisticsProxyModel Class Reference

`from PyKDE4.akonadi import *`

Inherits: QSortFilterProxyModel → QAbstractProxyModel → QAbstractItemModel → QObject
Namespace: Akonadi

## Detailed Description

A proxy model that exposes collection statistics through extra columns.

This class can be used on top of an EntityTreeModel to display extra columns summarizing statistics of collections.

       Akonadi.EntityTreeModel *model = new Akonadi.EntityTreeModel( ... );

       Akonadi.StatisticsProxyModel *proxy = new Akonadi.StatisticsProxyModel();
       proxy->setSourceModel( model );

       Akonadi.EntityTreeView *view = new Akonadi.EntityTreeView( this );
       view->setModel( proxy );

## Method Documentation

__init__ | ( | self, |
|  | QObject | parent=0
| ) |  |  |

Creates a new statistics proxy model.

Parameters:

  | parent | The parent object.

| ) |  |  |

bool isExtraColumnsEnabled | ( |  | self ) |

Return true if we display extra statistics columns, otherwise false

bool isToolTipEnabled | ( |  | self ) |

Return true if we display tooltips, otherwise false
